Version 1.0.5 was a hotfix released on August 4th, 2016. It was deployed two days after Version 1.0.4 and was pushed to resolve a bug which could cause character files to become corrupted. This patch fixed the bug and uncorrupted any characters which had been impacted by it as well.
It was announced and changes were detailed on the developer blog shortly after release.
We hadn’t intended to put out another patch so soon, but an odd bug was reported on the forums – putting an item in the hotbar, then placing it in the trash slot in your inventory, and then exiting the inventory window before the item was finished being removed was causing player files to become corrupted.
That’s fixed now! Any character that was broken by this specific bug should also be fixed, and should reappear in your character select screen.
